The control unit is connected to the head unit 120 and the coil unit 150, and the control unit can control the head unit 120 and the coil unit 150 to move according to printing information input from the user terminal. The control unit can measure the length used by unwinding from the supply unit 151 of the coil unit 150.

The control unit directly outputs a printing signal to the head unit 120 and the coil unit 150 based on the printing information stored in the storage device, thereby improving printing speed.

The head portion 120 outputs print information of the user terminal and is located between the overarm 113 and the base 111 and coupled to the lower surface of the overarm 113. The head portion 120 may have a lifting structure. The head unit 120 may descend to output print information.

As shown in FIG. 2, the head portion 120 has a near edge structure in which there is a heat wire 121 on the head so that the foil and the head are immediately separated after printing, thereby preventing post-heating. Accordingly, the digital foil printing device 100 can print print information on a printed matter (2) with a rough surface or a printed material (2) with a smooth surface and gloss.

Meanwhile, the head unit 120 may output printing information using a known dot printer method.

Additionally, the head portion 120 may have a structure that can move in the left and right directions. Accordingly, the head portion 120 can move in a three-axis structure.

The table 140 is located below the head portion 120 and is coupled to the base 111. A printed material 2 may be placed on the table 140. The surface of the printed matter 2 may be glossy and smooth or rough.

The table 140 can be moved forward, backward, left and right to adjust the printing position of the printed matter 2. A fixing means (not shown) such as a clip for fixing the printed matter 2 is disposed on the table 140. The width of such table 140 may be 186,000 mm2 to 204,600 mm2. The width of table 140 may be 195,200㎟. The width of the table 140 is not limited and may vary depending on the design of the digital foil printing device 100.

The printing area on the table 140 may be 100,000 mm2 to 175,000 mm2. The printing area on table 140 may be 135,000 square meters. The printing area may vary depending on the width of the table 140.

Meanwhile, a printing unit (not shown) that supplies and discharges the printed matter 2 may be placed on one side of the table 140. Printed matter can be automatically supplied to and retrieved from the table 140 through the printing unit.

The coil unit 150 includes a supply unit 151 and a recovery unit 152. The supply unit 151 and the recovery unit 152 face each other with the head unit 120 in between. The supply unit 151 and the recovery unit 152 are formed in the form of rollers and are rotatably coupled to the head unit 120. Here, the supply unit 151 can rotate freely without power, and a motor (not shown) is coupled to the recovery unit 152.

A foil (ribbon) 1 is wound around the supply unit 151. The foil may pass between the head portion 120 and the printed material 2 while being in contact with the head portion 120. The foil that has passed is wound in the recovery unit 152. When the recovery unit 152 is rotated by the motor, the foil is wound around the recovery unit 152 while passing through the lower part of the printing plate 130, and the foil in the supply unit 151 can be released. When the head portion 120 is lowered, the foil 1 may come into contact with the printed matter 2.

And a tension roller 153 is disposed between the supply unit 151 and the head unit 120, and between the recovery unit 152 and the head unit 120. The tension roller 153 is non-powered and is rotatably disposed on the head 120. The tension roller 153 is rotated by the moving foil and supports the foil 1 to maintain tension. The outer circumference of the tension roller 153 in contact with the foil is made of rubber. The rubber increases the contact between the tension roller (153) and the foil (1) and prevents the tension roller (153) from slipping on the foil (1).

Meanwhile, an encoder capable of measuring the degree of loosening of the foil 1 may be placed on the roller of the supply unit 151. Additionally, a counter sensor may be connected to the supply unit 151.

Meanwhile, an input unit 113a connected to the control unit is disposed on the overarm 113. Setting values according to foil printing may be input through the input unit 113a.

The display unit 160 includes a liquid crystal display (LCD) and can display (output) print information. The display unit 160 is disposed on the side of the overarm 113. However, the display unit 160 may be disposed on the front or upper surface of the overarm 113. The display unit 160 may be formed in a large size by being entirely disposed on the side or top surface. However, the display unit 160 can be made small by being partially disposed on the side or top. The size of the display unit 160 may vary depending on the design of the digital foil printing device 100.

The display unit 160 is connected to the control unit. Foil printing information may be displayed on the display unit 160 according to a signal from the control unit. Additionally, print information output from the user terminal may be displayed on the display unit 160. The display unit 160 may display printing information such as power on/off, print preparation, print progress, print end, number of prints, doctor's length, and total print length. Doctor's length (printing length can be displayed in meters (m). As the doctor's length is displayed on the display unit 160, the printer can visually check the doctor's length. Accordingly, the foil can be replaced quickly.

Meanwhile, the display unit 160 may have a touch panel function. Accordingly, printing information can be directly input using the display unit 160 without using the user terminal.

Next, the operation of the digital foil printing device described above will be explained.

The foil of the supply unit 151 is coupled to the recovery unit 152 via the tension roller 153 and the head unit 120, and the printed matter 2 is placed and fixed on the table 140. The printed matter 2 and the head portion 120 may face each other.

When the printer turns on the power switch, the display unit 160 displays letters indicating that printing is in progress and numbers indicating the printing length (amount of paper used). The printer uses the user terminal to input printing information, such as shapes and characters to be printed, into the control unit. The printer can input settings for printing through the input unit 113a.

The control unit that receives the output signal from the user terminal lowers the head portion 120 so that the foil 1 comes into contact with the printed matter 2. The motor is controlled to drive, and when the recovery part 152 rotates due to the driving of the motor, the foil (1) is released from the supply part (151), and the foil (1) passes while contacting the tension roller (153) and the head part (120). It is wound around the recovery unit (152). At this time, the print information output from the head unit 120 is printed on the printed matter 2.

And since the head portion 120 has a near-edge head structure, the foil 1 can be printed on the smooth or rough surface of the printed material 2.

And as the print information is output from the head unit 120, the table 140 can move in the left and right directions. However, the head portion 120 may move directly in the left and right directions.

During the printing process, characters indicating that printing is in progress are displayed on the display unit 160, and the printing length is output. Accordingly, the printer can check the printing status through the display unit 160, which has the effect of improving printing workability.

Next, another embodiment of the present invention will be described with reference to FIGS. 2 and 3.

Figure 2 is a schematic diagram showing a digital foil printing device according to another embodiment of the present invention, and Figure 3 is a schematic diagram showing the operating state of the display unit of Figure 2.

The digital foil printing device 200 according to another embodiment of the present invention has most of the components of the embodiment described with reference to FIG. 1. However, the digital foil printing device 200 according to this embodiment may further include a rotation unit 170 connected to the display unit 160.

The rotating unit 170 of the digital foil printing device 200 according to this embodiment includes a direction control unit 171, a bearing 172, and a shaft 173, and sets up the display unit 160 and adjusts the direction.

The direction control unit 171 is formed in a plate shape and is disposed on the upper surface of the overarm 113. The direction control unit 171 is disposed on one side of the upper surface of the overarm 113. The display unit 160 is connected to one end of the direction control unit 171 with a hinge 174. The display unit 160 can be erected based on the hinge 174. At this time, the display unit 160 can be erected while rotating in stages.

The bearing 172 is disposed on the overarm 113. The outer ring of the bearing 172 is fixed to the overarm 113.

The shaft 173 protrudes from the lower surface of the direction control unit 171 and is coupled to the inner ring of the bearing 172.

The direction control unit 171 is supported by the bearing 172 and can rotate on the overarm 113, and the direction of the erected display unit 160 can be changed. Since the display unit 160 is directed to the place where the printer is located by the rotation unit 170, the printer can check the printing status through the display unit 160 even at a location away from the digital foil printing device 200. This has the effect of improving printing workability.

Meanwhile, a motor (not shown) may be arranged parallel to the shaft 173. The drive shaft and shaft 173 of the motor are parallel and coupled to each other with teeth. The shaft 173 can rotate as the gears engage with each other due to the driving of the motor. Accordingly, since the rotating part is driven by a motor, operability according to the change of direction of the display part 160 is improved.

And printing information may be output to the display unit 160 according to this embodiment. Accordingly, the user can compare the print information printed on the printed matter 2 with the print information output on the display unit 160 and check for output errors in the print information.

Many features discussed in the embodiment shown in FIG. 1 can be applied to this embodiment.
